Detailed Description

In general, the attachment devices of the various embodiments described herein are used to attach to structural components. The attachment device may be fixed to any structural element of a building, such as a beam, floor, ceiling. In the illustrated embodiment, the attachment device is secured to the i-joist. Any suitable restraint or anti-sway support (such as a longitudinal or lateral anti-sway support/restraint) may be attached to the attachment device to secure the non-structural component to the structural component. The various attachment devices are each configured to securely attach to a structural component (i.e., an i-joist/sawn timber) and provide a raised attachment location for mounting an accessory to the attachment device. Thus, the attachment device is configured to mount the accessory at a position that does not interfere with surrounding components of the structural component. Additionally, one or more of the attachment devices provide attachment to the structural member without forming a pre-drilled hole through the structural member. Thus, the attachment device is configured to maintain the strength and integrity of the structural component after attachment to the structural component.

Referring to FIG. 1, one example of a suitable anti-roll support or restraint that may be used with the various attachment devices described below is indicated generally by the reference numeral 10. As is generally known in the art, the anti-sway support/restraint 10 includes a strut 12 (e.g., a pipe, bar, rod, etc.) and opposing connection fittings 14 at each end of the strut. One connection fitting 14 may be used to attach the anti-sway support/restraint 10 to a structural component (e.g., an i-joist of a building) and the opposite connection fitting 14 may be used to attach the anti-sway support/restraint to a non-structural component (e.g., a pipe, a conduit, a pipe, a fitting, etc.). When the attachment device is coupled to the non-structural component, the anti-sway support/restraint spans between the structural component and the non-structural component, thereby supporting the non-structural component in the building. In the illustrated embodiment, each of the connection fittings 14 is identical and defines a fastener opening 16 that can be used to connect the connection fitting to any of a variety of attachment devices, as described in more detail below. It should be understood that the anti-roll support/restraint 10 in fig. 1 is exemplary and that the various attachment devices of the present disclosure may be used with any suitable anti-roll support/restraint. For example, the anti-roll support/restraint may be a seismic anti-roll support/restraint. Further, it is contemplated that any of the various attachment devices described below may be directly connected to the strut 12 of the sway brace/restraint 10 (e.g., replacing one of the connection fittings 14 at one end of the strut 12), as is generally known in the art.

Referring to fig. 2-4, a first embodiment of an attachment device for coupling to a structural member is indicated generally by reference numeral 20. As shown in fig. 2, the attachment device 20 is configured to attach to a structural member (such as a wooden i-joist J) and to a connection fitting 14 for attachment to a suitable anti-sway brace restraint or the like. The attachment device 20 includes a body or plate member 22 configured to be attached to the web W of the joist J. The plate member 22 has a planar portion 24 and a raised portion 26. The planar portion 24 provides a contact surface for engaging the web W of the joist J. In the illustrated embodiment, the attachment device 20, and in particular the plate member 22, has a rectangular shape. However, the attachment device 20 may be formed in any suitable shape, such as circular or oval, without departing from the scope of the present disclosure. A pair of slots in plate member 22 extend along the height of attachment device 20 between the top and bottom of the attachment device. The first slot 28 is disposed adjacent a first longitudinal end of the attachment device 20 and the second slot 29 is disposed adjacent a second longitudinal end of the attachment device. In the illustrated embodiment, each

slot

28, 29 comprises a continuous slot. However, each of the

slots

28, 29 may include a plurality of discrete slots spaced along the height and/or length of the plate member 22. One or more fasteners 30 are received in the

slots

28, 29 for securing the attachment device 20 to the web W of the joist J. In one embodiment, the fastener 30 is a self-tapping wood screw configured to drill into a wooden joist J. Thus, no pre-drilled holes are formed in the joists J for receiving standard bolts.

The raised portion 26 is disposed inwardly of the planar portion 24 such that the raised portion is surrounded on all sides by the planar portion. In the illustrated embodiment, the raised portion 26 comprises a circular protrusion including a curved peripheral edge 32 protruding away from the planar portion 24 and a planar engagement surface 34 defined by the peripheral edge. Thus, the planar engagement surface 34 lies in a plane that is spaced from the plane of the planar portion 24 in a direction extending orthogonally to both planes. The holes (not shown) are configured to receive fasteners (not shown) for attaching the fitting 14 to the attachment device 20. Thus, the fitting 14 is spaced from the web W of the joist J a sufficient amount to prevent the fitting from engaging the flange F. This allows the accessory 14 to be attached to the attachment device 20 in any desired angular orientation. The fitting 14 can also be attached to the attachment means 20 without making a through hole in the web W of the joist J. While the raised portion 26 is shown as a lobe, it should be understood that the raised portion may have other configurations without departing from the scope of the present disclosure.

The attachment device 20 may be considered a first attachment device and is configured for attachment to a first face of the web W of the joist J. Referring to fig. 3 and 4, the second attachment device 20A is configured for attachment to an opposite face of the web W of the joist J. The second attachment device 20A is substantially similar to the first attachment device 20. However, in addition to the

slots

28A, 29A, the second attachment device 20A includes a hook member 36A disposed at each end of the slot. Each hook 36A includes a first arm extending orthogonally from the planar portion 24A and a second arm extending generally parallel to the planar portion. The block member 38A is held to the second attachment device 20A by the hook member 36A. In particular, the block member 38A has a height extending parallel to the planar portion 24A and a thickness extending perpendicular to the planar portion 24A such that the block member is sized and shaped to be received within the space formed by the hook member 36A and the planar portion 24A. Thus, the first arm of the hook member 36A engages the top and bottom sides of the block member 38A, respectively, and the second arm of the hook member engages the outward surface of the block member to hold and retain the block member to the second attachment device 20A. In one embodiment, the block member 38A comprises wood, plastic, or a composite material. Other materials for the block members are also contemplated.

When the fastener 30 is inserted through the

slots

28, 29 in the first attachment means 20, the fastener will pass through the web W of the joist J, through the

slots

28A, 29A in the second attachment means 20A, and into the block member 38A. Thus, the self-tapping wood screw 30 is anchored in the block member 38A. The fastening engagement between the fastener 30 and the block member 38A secures both the first attachment device 20 and the second attachment device 20A to the web W of the joist J. In addition, the block member 38A is thicker than the web W of the joist J and thus provides a more robust and mechanically reliable structure for receiving fasteners than would be possible using only the web W of the joist J.

Referring to fig. 5, a second embodiment of an attachment device for attachment to a structural member is indicated generally by the reference numeral 120. The attachment device 120 is configured to attach to a structural component (such as a wooden i-joist J) and to a connection fitting 14 for attachment to a suitable anti-sway brace restraint or the like. The attachment device 120 includes a body or plate member 122 configured to be attached to the web W of the joist J. The plate member 122 has a planar portion 124 and a raised portion 126. The planar portion 124 provides a contact surface for engaging the web W of the joist J. In the illustrated embodiment, the attachment device 120, and in particular the plate member 122, has a rectangular shape. However, the attachment device 120 may be formed in any suitable shape, such as circular or oval, without departing from the scope of the present disclosure. The fastener holes in the panel member 122 are configured to receive fasteners 130 for securing the attachment device 120 to the web W of the joist J. In one embodiment, the fasteners 130 are wood screws configured to drill into the wooden joists J. Thus, no pre-drilled holes are formed in the joists J for receiving standard bolts.

The raised portion 126 is generally disposed in the middle of the planar portion 124 such that the raised portion is surrounded on both sides by the planar portion. In the illustrated embodiment, the raised portion 126 comprises a generally rectangular or trapezoidal protrusion including curved longitudinal edges 132 protruding away from the planar portion 124 and a planar engagement surface 134 between the longitudinal edges. Thus, the planar engagement surface 134 lies in a plane that is spaced from the plane of the planar portion 124 in a direction extending orthogonally to the two planes. A post 140 extends from the planar engagement surface 134 for attaching the accessory 14 to the attachment device 120. Thus, the fitting 14 is spaced from the web W of the joist J by a sufficient amount to prevent the fitting from engaging the flange F. This allows the accessory 14 to be attached to the attachment device 120 in any desired angular orientation. The fitting 14 can also be attached to the attachment means 120 without making a through hole in the web W of the joist J. While the raised portion 126 is shown as a rectangular or trapezoidal protrusion, it should be understood that the raised portion may have other configurations without departing from the scope of the present disclosure.

The attachment device 120 may be considered a first attachment device and is configured for attachment to a first face of the web W of the joist J. Referring to fig. 6, a second attachment device 120A is configured for attachment to an opposite face of the web W of the joist J. The second attachment device 120A includes a block member 138A. In one embodiment, the block member 138A comprises wood, plastic, or a composite material. Other materials for the block members are also contemplated. When the fastener 130 is inserted through the fastener hole in the first attachment device 120, the fastener will pass through the web W of the joist J and into the block member 138A. Thus, the self-tapping wood screw 130 is anchored in the block member 138A. The fastening engagement between the fastener 130 and the block member 138A secures both the first attachment device 120 and the second attachment device 120A to the web W of the joist J. In addition, the block member 138A is thicker than the web W of the joist J and thus provides a stronger and mechanically reliable structure for receiving fasteners than would be possible using only the web W of the joist J.

Referring to fig. 7 and 8, a third embodiment of an attachment device for attachment to a structural member is indicated generally by the reference numeral 220. The attachment device 220 is configured to attach to a structural member (such as a wooden i-joist J) and to a connection fitting 14 for attachment to a suitable anti-sway brace restraint or the like. The attachment device 120 includes a body or plate member 222 configured to be attached to the web W of the joist J. The plate member 222 has a convex portion 226 and a plurality of planar portions 224. The planar portion 224 provides a contact surface for engaging the web W of the joist J. In the illustrated embodiment, the plate member 222 has a generally T-shape. However, the plate member 222 may be formed in any suitable shape, such as circular or rectangular, without departing from the scope of the present disclosure. The fastener holes in the panel member 222 are configured to receive fasteners 230 for securing the attachment device 220 to the web W of the joist J. In one embodiment, the fastener 230 is a standard bolt fastener.

The raised portion 226 is disposed in the middle of the planar portion 224 such that the raised portion is surrounded by the planar portion on the top, bottom, left, and right sides. In the illustrated embodiment, the raised portion 226 comprises a rectangular projection including curved side edges 232 projecting away from the planar portion 224 and a planar engagement surface 234 between the side edges. Thus, the planar engagement surface 234 lies in a plane that is spaced from the plane of the planar portion 224 in a direction extending normal to both planes. A post 240 extends from the planar engagement surface 234 for attaching the accessory 14 to the attachment device 220. Thus, the fitting 14 is spaced from the web W of the joist J a sufficient amount to prevent the fitting from engaging the flange F. This allows the accessory 14 to be attached to the attachment device 220 in any desired angular orientation. The fitting 14 can also be attached to the attachment means 220 without making a through hole in the web W of the joist J. While the raised portion 226 is shown as a rectangular protrusion, it should be understood that the raised portion may have other configurations without departing from the scope of the present disclosure.

Referring to fig. 9, a fourth embodiment of an attachment device for attachment to a structural member is indicated generally by the reference numeral 320. The attachment means 320 is configured to attach to a structural component (such as a wooden i-joist/sawn timber) and to a connection fitting 14 for attachment to a suitable anti-sway support restraint or the like. The attachment device 320 includes a body or plate member 322 configured to attach to the web W of the joist. The plate member 322 has a planar portion 324 and a raised portion 326. The planar portion 324 provides a contact surface for engaging the web W of the joist. In the illustrated embodiment, the attachment device 320, and in particular the plate member 322, has a rectangular shape. However, the attachment device 320 may be formed in any suitable shape, such as circular or oval, without departing from the scope of the present disclosure. Fastener holes (not shown) in the plate members 322 are configured to receive fasteners 330 for securing the attachment devices 320 to the webs W of the joists. In one embodiment, the fastener 330 is a standard bolt fastener.

The raised portion 326 is disposed inside the planar portion 324 such that the raised portion is surrounded on all sides by the planar portion. In the illustrated embodiment, the raised portion 326 comprises a circular protrusion including a curved peripheral edge 332 protruding away from the planar portion 324 and a planar engagement surface 334 defined by the peripheral edge. Thus, the planar engagement surface 334 lies in a plane that is spaced from the plane of the planar portion 324 in a direction extending orthogonally to the two planes. The holes (not shown) are configured to receive fasteners 340 for attaching the accessory 14 to the attachment device 320. Thus, the fitting 14 is spaced from the web W of the joist a sufficient amount to prevent the fitting from engaging the joist flange. This allows the accessory 14 to be attached to the attachment device 320 in any desired angular orientation. While the raised portion 326 is shown as a circular protrusion, it should be understood that the raised portion may have other configurations without departing from the scope of the present disclosure.

Referring to fig. 10, a fifth embodiment of an attachment device for attachment to a structural member is indicated generally by the reference numeral 420. The attachment device 420 is configured to attach to a structural component (such as a wooden i-joist J) and to a connection fitting 14 for attachment to a suitable anti-sway brace restraint or the like. The attachment device 420 includes a body or plate member 422 configured to attach to the web W of the joist J. The plate member 422 has a planar portion 424 and a raised portion 426. The planar portion 424 provides a contact surface for engaging the web W of the joist J. In the illustrated embodiment, the attachment device 420, and in particular the plate member 422, has a rectangular shape. However, the attachment device 420 may be formed in any suitable shape, such as circular or oval, without departing from the scope of the present disclosure. Fastener holes (not shown) in the plate member 422 are configured to receive fasteners 430 for securing the attachment device 420 to the web W of the joist. In one embodiment, fastener 430 is a standard bolt fastener.

The raised portion 426 is generally disposed in the middle of the planar portion 424 such that the raised portion is surrounded on both sides by the planar portion. In the illustrated embodiment, the raised portion 426 comprises a generally rectangular or trapezoidal protrusion including curved longitudinal edges 432 that protrude away from the planar portion 424 and a planar engagement surface 434 between the longitudinal edges. Thus, the planar engagement surface 434 lies in a plane that is spaced from the plane of the planar portion 424 in a direction extending orthogonally to the two planes. The holes (not shown) are configured to receive fasteners 440 for attaching the fitting 14 to the attachment device 420. Thus, the fitting 14 is spaced from the web W of the joist J a sufficient amount to prevent the fitting from engaging the flange F. This allows the accessory 14 to be attached to the attachment device 420 in any desired angular orientation. The fitting 14 can also be attached to the attachment means 420 without making a through hole in the web W of the joist J. While the raised portion 426 is shown as a rectangular or trapezoidal protrusion, it should be understood that the raised portion may have other configurations without departing from the scope of the present disclosure.

In addition, flanges 450 extend laterally from the bottom edge of the plate member 422 on opposite sides of the raised portion 426. The flange 450 provides a joining surface with the lower flange F of the joist J. To this end, the flange 450 supports the attachment device 420 under vertical load conditions. Thus, the overall size of the attachment device 420 is reduced while the load capacity of the attachment device is increased.

Referring to fig. 11, a sixth embodiment of an attachment device for attachment to a structural member is indicated generally by the reference numeral 520. The attachment means 520 is configured to attach to a structural member, such as a wooden i-joist J, and to a connection fitting for attachment to a suitable anti-sway support restraint or the like. The attachment device 520 includes a body or plate member 522 configured to attach to the web W of the joist J. The plate member 522 has a planar portion 524 and a raised portion 526. The planar portion 524 provides a contact surface for engaging the web W of the joist J. In the illustrated embodiment, the attachment device 520, and in particular the plate member 522, has a generally rectangular shape. However, the attachment device 520 may be formed in any suitable shape, such as circular or oval, without departing from the scope of the present disclosure. Fastener holes (not shown) in the panel member 522 are configured to receive fasteners 530 for securing the attachment device 520 to the web W of the joist J. In one embodiment, fastener 530 is a standard bolt fastener.

The raised portion 526 is disposed inwardly of the planar portion 524 such that the raised portion is surrounded on all sides by the planar portion. In the illustrated embodiment, the raised portion 526 includes a circular protrusion that includes a curved peripheral edge 532 that protrudes away from the planar portion 524 and a planar engagement surface 534 defined by the peripheral edge. Thus, the planar engagement surface 534 lies in a plane that is spaced from the plane of the planar portion 524 in a direction extending normal to both planes. Posts 540 extend from planar engagement surface 534 for attaching accessory 14 to attachment device 520. Thus, the fitting 14 is spaced from the web W of the joist J by a sufficient amount to prevent the fitting from engaging the flange F. This allows the accessory 14 to be attached to the attachment device 520 in any desired angular orientation. The fitting 14 can also be attached to the attachment device 520 without making a through hole in the web W of the joist J. While the raised portion 526 is shown as a circular protrusion, it should be understood that the raised portion may have other configurations without departing from the scope of the present disclosure.

In addition, a flange 550 extends laterally from the bottom edge of the planar portion 524 of the plate member 522. The flange 550 provides a joint surface with the lower flange F of the joist J. To this end, the flange 550 supports the attachment device 520 under vertical load conditions. Thus, the overall size of the attachment device 520 is reduced while the load capacity of the attachment device is increased.

Referring to fig. 12 and 13, a seventh embodiment of an attachment device for attachment to a structural member is indicated generally by the reference numeral 620. The attachment means 620 is configured to attach to a structural member (such as a wooden i-joist J) and to a connection fitting 14 for attachment to a suitable anti-sway support restraint or the like. The attachment means 620 includes a body or plate member 622 configured to be attached to the web W of the joist J. Plate member 622 has a planar portion 624 and a raised portion 626. The flat portion 624 provides a contact surface for engaging the web W of the joist J. In the illustrated embodiment, the attachment device 620, and in particular the plate member 622, has a rectangular shape. However, the attachment device 620 may be formed in any suitable shape, such as circular or oval, without departing from the scope of the present disclosure. Fastener holes (not shown) in the plate member 622 are configured to receive fasteners 630 for securing the attachment device 620 to the web W of the joist. In one embodiment, the fastener 630 is a standard bolt fastener.

Raised portion 626 is generally disposed in the middle of planar portion 624 such that the raised portion is surrounded on both sides by the planar portion. In the illustrated embodiment, the raised portion 626 includes a generally rectangular or trapezoidal protrusion including curved longitudinal edges 632 protruding away from the planar portion 624 and a planar engagement surface 634 between the longitudinal edges. Thus, the planar engagement surface 634 lies in a plane that is spaced from the plane of the planar portion 624 in a direction extending orthogonally to the two planes. The holes (not shown) are configured to receive fasteners 640 for attaching the fitting 14 to the attachment device 620. Thus, the fitting 14 is spaced from the web W of the joist J by a sufficient amount to prevent the fitting from engaging the flange F. This allows the accessory 14 to be attached to the attachment device 620 in any desired angular orientation. While the raised portion 626 is shown as a rectangular or trapezoidal protrusion, it should be understood that the raised portion may have other configurations without departing from the scope of the present disclosure.

In addition, flanges 650 extend laterally from the bottom edge of the plate member 622 on opposite sides of the raised portion 626. The flange 650 provides an engagement surface with the lower flange F of the joist J. To this end, the flange 650 supports the attachment means 620 under vertical load conditions. Thus, the overall size of the attachment device 620 is reduced and at the same time the load capacity of the attachment device is increased.

The attachment device 620 may be considered a first attachment device and is configured for attachment to a first face of the web W of the joist J. Referring to fig. 13, a second attachment device 620A is configured for attachment to an opposite face of the web W of the joist J. When the fastener 630 is inserted through the fastener hole in the first attachment means 620, the fastener will pass through the web W of the joist J and into the fastener hole in the second attachment means 620A.

Referring to fig. 14, an eighth embodiment of an attachment device for attachment to a structural member is indicated generally by the reference numeral 720. The attachment device 720 is configured to attach to a structural component (such as a wooden i-joist J) and to a connection fitting 14 for attachment to a suitable anti-sway brace restraint 10 or the like. The attachment device 720 includes a body or plate member 722 configured to attach to the web W of the joist J. The plate member 722 has a planar portion 624 and a raised portion 726. The flat portion 724 provides a contact surface for engaging the web W of the joist J. In the illustrated embodiment, the attachment device 720, and in particular the plate member 722, has a generally rectangular shape. However, the attachment device 720 may be formed in any suitable shape, such as circular or oval, without departing from the scope of the present disclosure. Fastener holes (not shown) in the plate member 722 are configured to receive fasteners 730 for securing the attachment device 720 to the web W of the joist J. In one embodiment, the fastener 730 is a twist-shear type nut/bolt fastener for visually verifying the desired torque to be applied.

The raised portion 726 is disposed generally in the middle of the planar portion 724 such that the raised portion is surrounded on both sides by the planar portion. In the illustrated embodiment, the raised portion 726 includes a generally trapezoidal protrusion including planar longitudinal edges 732 that protrude at an angle away from the planar portion 724 and a planar engagement surface 734 between the longitudinal edges. Thus, the planar engagement surface 734 lies in a plane that is spaced from the plane of the planar portion 724 in a direction extending normal to both planes. The holes (not shown) are configured to receive fasteners 740 for attaching the fitting 14 to the attachment device 720. Thus, the fitting 14 is spaced from the web W of the joist J a sufficient amount to prevent the fitting from engaging the flange F. This allows the accessory 14 to be attached to the attachment device 720 in any desired angular orientation. The fitting 14 can also be attached to the attachment means 720 without making a through hole in the web W of the joist J. While the raised portion 726 is shown as a trapezoidal protrusion, it should be understood that the raised portion may have other configurations without departing from the scope of the present disclosure.

The first planar portion 825A provides a contact surface for engaging the web W of the joist J. The second planar portion 827A extends orthogonally to the first planar portion 825A and provides a contact surface for the top of the lower flange F of the joist J. The third planar portion 829A extends orthogonally to the second planar portion 825A and provides a contact surface for the side edge of the lower flange F of the joist J. The fourth planar portion 831A extends orthogonally to the third planar portion 829A and provides a contact surface for the bottom of the lower flange F of the joist J. The fifth planar portion 833A extends orthogonally to the fourth planar portion 831A. Fastener holes (not shown) in the fifth planar portion 833A are configured to receive fasteners 830 for securing the two

attachment devices

820, 820A to the joist J.
